RV 4.53.5
त्रिर् अन्तरिक्षं सविता महित्वना त्री रजांसि परिभुस् त्रीणि रोचना । तिस्रो दिवः पृथिवीस् तिस्र इन्वति त्रिभिर् व्रतैर् अभि नो रक्षति त्मना ॥
trir antarikṣaṃ savitā mahitvanā trī rajāṃsi paribhus trīṇi rocanā | tisro divaḥ pṛthivīs tisra invati tribhir vratair abhi no rakṣati tmanā ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Savitar thrice surrounding with his mightiness mid-air, three regions, and the triple sphere of light, Sets the three heavens in motion and the threefold earth, and willingly protects us with his triple law.
Translated by Ralph T. H. Griffith (1896)
